TOBACCO-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 792,453, dated. June 13, 1905.

Application filed August 27, 1903. Serial No. 170,941.

To all "1071,0717, it may concern.-

Be it known thatl, EDUARD Quns'rnn, a subject of the German Emperor, residing at Ber liu, Germany, (and whose post-oflice address is Marienstrasse 17, Berlin, Germany.) have invented certain new and useful Improvements in 'Iobacco-Gutting Machines; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention consists chiefly in a special construction of mouthpiece for tobacco-cutting machines.

In the present machines the lower fixed jaw and the upper movable jaw are fitted in the machine in such a way as to cause an irregular motion of the cutting parts and also frequently prevents the independent motion of the upper jaw and of the upper roller with respect to each other. These faults arise from the fact that the slide-groove in which the cutting parts work has defects which break its continuity, and thus stop parts of the cutting mechanism, and so interfere with the proper movements of the cutters and rollers.

The object of my invention is to facilitate and insure free motion of the upper jaw and of the upper roller, besides supplying a guide for the edges of the knife, and thus secure uninterrupted and completely smooth side guides for the cutting mechanism.

I will now describe my invention with reference to the accompanying drawings, in which- Figure 1 shows a vertical longitudinal section of the tobacco-machine on the line 1 1 of Fig. 2. Fig. 2 shows an elevation of same. Fig. 3 shows an enlarged section of the lower jaw or lower mouth part. Fig. 4 shows part of the lower jaw enlarged in front elevation. Fig. 5 shows an enlarged section of part of Fig. 2, taken on the line A B. Fig. 6 shows an enlarged vertical section of the upper jaw or upper mouth part on the line 6 6, Fig. 7, looking in the direction of the arrow. Fig. 7 shows an enlarged portion of the upper jaw in front elevation.

The wood drum (1 is placed in the machineframe 1). The three upper rollers b 0 (Z are journaled in the sides of the frame which moves on the pivot f, so as to enable the upper rollers to rise and fall as required. The trough consists of two side pieces or checks 6 and a bottom plate a. The knife-holder is supported by two levers 71/, which are also pivoted atf'. The knife-holder with the knife is raised and let down by a eonnecting-rod 71, which is actuated by a crank-shaft driven by the pulley Z1. My improved mouthpiece consists of a movable upper jaw 92., connected to the side cheeks e, and of a lower jaw on, fixed to the frame 12, the lower jaw at having two side guide-bars 0' standing vertically whose distance apart is exactly equal to the distance apart of the two side pieces of the trough. Two flanges 0 are placed on the outside of the two guide-bars 0', which are fastened to corresponding flanges g of the frame p. These bars have their front and rear faces on the arc of a circle having the pivot f as a center.

Between the two guide-bars r is fitted the upper jaw a level with the front face of the guide-bars 'r, Fig. 2, which upper jaw travels in a segmental path concentric with the pivot f. The sliding place for the edges of the knife 5 is formed along the front face of the upper jaw a, the two guide-barsr, and the lower jaw m. The length of the guide-bars? is so arranged that their top ends are always able to come in lateral contact with the upper jaw n when in its highest position.

6 is a weighted lever attached to the upper jaw by a link for holding it down upon the tobacco-leaves.

It is to be understood that the upper jaw 02. is movable with the trough, and hence partakes of the same movement.

The flanges s of the ledges o (the flanges w of which have openings, as seen in Figs. 5, 6, and 7) are behind the front edges of the upper jaw 77/ and are about the distance apart of the thickness of the guide-bars 0' and come directly in contact with the back edges of the latter, whereas the distance apart of the ledges o is equal to the distance apart of the guide-bars), and to those of the side cheeks e and the length of the side ledges o are such that the lower edges of the side ledges w are able even when the upper jaw a and the rollers 7/, c, and (Z are at their highest position to eX tend below the upper edge of the lower jaw in and the bottom plate a, which is stationary with relation to the side pieces, so that no open spaces can be formed about the side corners of these parts when raising and lowering the upper jaw and the upper rollers.

The material is fed forward by the revolution of the drum a. The jaws mm constitute the mouthpiece.

In operation the knife is reciprocated through the medium of the rod 1' and the crank-shaft operated by the pulley I: from any suitable source, the rollers are revolved by their gear-wheels, which are arranged to intermesh, as seen in Fig. 2, and the rollers and the upper jaw 92 are moved about the pivotf as a center, and the guide-bars 1' serve as a guide for the back side of the knife in its reciprocations. The knife is kept in contact with the bars r by means of the levers /1/, which carry the knife-holder.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a tobacco-cutting machine, the combination with the upper forward impelling-roller b, of an upper jaw, and pivoted checks, the roller and the upperjaw being connected with the said pivoted cheeks and having upward movement therewith, and a lixed lower jaw having flanges for cooperation with the upper jaw.

2. In a tobacco-cutting machine having a knife supported to oscillate, the combination with the upper forward impelling-roller 7), of an upper jaw, and pivoted cheeks, the roller and the upper jaw being connected with the said pivoted cheeks and having upward move ment therewith, and a fixed lower jaw having flanges for cooperation with the upper jaw, said flanges being disposed behind the front face of the upper jaw.

3. An improved mouthpiece for a tobaccocutting machine comprising an upper jaw connected to move with the upper forward impelling-roller Z), side cheeks, a fixed lower jaw, having vertical side guide-bars disposed at a distance apart equal to the distance apart of the side cheeks, flanges on the outside of said guide bars, corresponding flanges on the frame, the upper jaw being fitted behind said guide-bars and movable in a segmental path concentric with the pivot of the knife-holder, side ledges on the upper jaw having curved front flanges disposed behind the front edges of the upper jaw, and side flanges on said ledges, connected to the said side checks, all substantially as and for the purpose specilied.

In testimony whereof I aflix my signature.

EDUARD QUES'JTER.
